Summary: In this study, dense thin films of TiO2 and TiO2 doped with Zr4+ were prepared using spin coating on glass substrate and characterized. The results showed that doping Zr4+ can change the optical and crystalline structure properties of TiO2, with higher doping concentration leading to lower band gap energy, slight lattice enlargement, and smaller crystal size. Additionally, the doped films exhibited typical photoluminescence in the visible spectrum region and had a lower rate of electron-hole recombination.

Summary: The structural parameters, dynamic stability, electronic, and optical properties of Zn1-xCdxTe, Zn1-xHgxTe, and Cd1-xHgxTe ternary alloys were systematically studied. These ternary alloys were found to be dynamically stable. Direct electronic transitions were allowed at the Gamma point for all compounds. The band gap energy showed a drastic decrease from ZnTe to HgTe. By alloy engineering, the band gap energy could be varied in a wide range of 0-2 eV. Several novel compounds exhibited suitable band gaps (1.3-1.6 eV) and good carrier mobility for potential optoelectronic applications. Optical properties were compared in the visible region, and an improvement in the absorption coefficient was observed for Zn0.75Hg0.25Te and Cd0.75Hg0.25Te. This study will contribute to the discovery of desired materials with low toxicity and high efficiency for solar cells.

Summary: This study presents a new design of van der Waals heterogeneous single-atom catalysts (vdW-SACs) for electrocatalytic nitrogen reduction reaction (eNRR). Large-scale density functional theory (DFT) calculations were employed to investigate the stability, NRR activity, and selectivity of these vdW-SACs. It was found that the W-C3/P-C3 catalyst exhibits the highest activity with the lowest overpotential due to the asymmetric active sites and the pd hybridization between W 5d orbitals and N2 π* antibonding orbitals. This research provides new insights for the development of advanced electrocatalysts for NRR and beyond.

Summary: This study reveals for the first time the energetic stability, elastic parameters, electronic structures, effective masses, and optical properties of BaM2As2 (M = Mg, Zn, Cd) and their alloys. The preferred phase for BaMg2As2 and BaCd2As2 is trigonal, while BaZn2As2 may have an additional stable trigonal phase. The dynamical stability is identified for four novel compounds, and their mechanical stability is confirmed. The band gap energy decreases significantly from BaMg2As2 (1.64 eV) to BaCd2As2 (0.80 eV). Different electronic properties are found for three phases of BaZn2As2. The band gap calculations agree with experimental results. The bandgap transition behavior and optoelectronic properties of three alloys are disclosed, with Ba(Mg0.5Zn0.5)2As2 and Ba(Mg0.5Cd0.5)2As2 showing desirable optoelectronic properties. These findings are expected to assist in discovering novel stable inorganic compounds for potential photovoltaic applications.

The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
